, MALTED-MILK DISPENSER AND MIXER.

Application filed. March 26, 1921.` Serial LNo. 455,937.

To all whom t may concer/n,

Be it known that I, JOSEPH A. FRANKLIN,

a citizen ofthe United Statesfresiding at Chicago, inthe county of.v Cook and kState of Illinois, have invented certain new and yuseful Improvements in Malted-lVIilk Dispensers and Mixers, of which tlie`following is a specification. f

This invention relates to acombined device for dispensing and mixing inalted milk and like drinks at soda fountains andsimilar places'where mixed drinks of this char-, acter are dispensed; and the main object of the invention `is to produce a simple, r-inexpensive and efficient device'by which meas ured charges of lmalted milk 'or similar powdered materialv may be depositedin the mixing cup, and after tliemilksyrups and other ingredientsof the mixture have been added, be vthoroughly stirred.-

Another object of theinvention is toprovide a new and'improved combined struc-k ture of malted milk container, dispenser-,Y mixer and mixing cup holder or support,"

which shall effect an economy of space at the soda fountain, and simplify the operations involved in preparing the ,drink for the customer.r y

In carryingout my/invention, Iprovide a suitable casing-mounted Ona lpost that may be clamped for 'otherwise lsecured to the counter, .ak malted milk lholder or receptacle mounted on and at its lower endfopen tothe dispensing lmechanism in 4said' casing, a crank operatedmechanism in' saidk casing for delivering ameasured charge ofk malted milk ateachl'coinplete turn ofthe crank, ,an electric `motor attached .to one side; of said casing and directly drivinga de` illustrated in the accompanying drawing one embodiment thereof which hasbeen found in practice tosatisfactorily effect the viewed from the left of Fig. 1;

beclearlyl understood by those skilled in the art I have l ring theretoy Fig. lisa front elevation ofmy improved dispenser `and mixer;

Fig. 2 is a side elevation of the same, as

Fig. 3 is an enlarged horizontal section taken on the line 3-'3 of Fig. 1 Fig. 4 is a similar section taken on the line 4-4 of Fig. 1; vFig. 5 is a central vertical section taken on the line 5,5 of Fig. 2;V

Fig. 6 is a horizontal section taken on the line 6-6 of Fig. 1; and

Figs. 7, 8 and 9 are enlarged vertical sections taken through the measured charge delivery device, illustrating different positions of the rotary valve.

Referring t0 the drawing-`v `l() designates a round post or standard, rigid with the lower end of which isaclamp 11by which it may be securely mountedon a counter or table 12. Secured on top of the -post 10, as byl a boltl 13 5) is a cupand 17, respectively. A portion ofthe lower chamber 17 is dividedofli' bya flatf'vertical partition 18 and circular side walls 19 'to form a chamber 20 that lcommunicates through an opening 21 in the partition 15 with the upper chamber 16 of the casing; The vertical wall of the upper chamber 16 is counter-sunk, as shown at 22 to receive and support the loweropen end "of a glass ask 23 which contains the malted milk or other material'to be dispensed, and has at its upper end an open neck 24 that maybe closed by a glass stopper 25'. f

Journaled 'nand yacross jthe lower chamber 17 of the casing' is a horizontal shaft 26 provided on one 4vend -with a cra-nk arm 27 and a handle 28.- The shaft 26 yextends through the discharge chamber 2O and has a threaded end 26 which screws into a nut 29 that is rotatably mounted in a cover plate 30 fitting and closing a circular opening 31 (Fig. 2) in the side wall of ltlfiecasing 14, said cover plate` being held against turning whenthe crank is turned by a locking lug loo 32 engaged with a notch 83 in the edge of the opening 3l.

Keyed on the shalt 26 is a miter gear d that meshes with and drives a miter gear 35 tast on the lower end of a vertical spindle 36 that is journaled in the partition 15 and has keyed thereon a sweep 37` ig. 3), the farms of which successively sweep across the disel'iarge opening 2l. v

On the upper end ot the spindle 3G is a radial arm 38 (Fig. 2) that constitutes an agitator or stirrer for the body olf material contained in the llask 23. Fast on the shaft 26 within the circular discharge chamber 20 is a rotary measuring valve 39, formed with a sector-shaped head LlO that lits and slidably engages with the interior circular wall of the casing, and alternately opens and closes at each revolution discharge port 19 in the lower end oi the circular wall 19 of the valve casing. ln the idle position ofthe device, the valve head Ll() closes and seals the discharge opening 19 against the entrance ol moisture which tends to cake the malted milk and prevent it from lio 'ing i`reely. At each complete revolution a fixed amount or charge is delivered by the valve.

Secured externally to the circular wall ot' the casing la, through an interposed block 4.1 of insulating material, is an electric motor designated as an entirety by The motor /l2 is supplied with. current through circuit wires 4&3, and il (Fig. which are led into the chamber 1"? on the opposite side 'of the casing from the motor, and include therein a circuit opening and closing switch designated generally by a5, the operating handle 45 of which extends through a slot d6 in the wall of the casing. The armature of the motor carries a' depending stirrer spindle 4l? having on its lower-end the usual mixing disc 4S.

lotatably and slidably mounted on the post. l() isa collar e9, to which is rigidly secured a radially ent-ending arm 50 terminating at its outer end in a broad flat seat 5l of su'lhcient size to form a rest or support for the bottom of the mixing cup or glass indicated by dotted lines at 52. On one 'side of the plate 5l is a rigid post 53, to which is secured a curved spring metal clip` or clamp 5dadapted to yieldingly em brace the drinking cup or glass 52 when the latter is placed upon the support 5l. The arm 50 is designed to swing to a limited extent sulhcient to carry the cup holder 'to and away from a position directly beneath the mixer spindle d?. For this purpose l have formed on the lower side or the arm 50 a pair of depending pins 55 and 56 (Fig. 2) which alternately engage with a stop lug 57 projecting from the post 10.

ln the use of my improved de rice, assuming that the flask 23 contains a' body ol? inalted milk or other powdered material to be dispensed as a drink ingredient, the mixing cup 52 is held beneath 'the discharge opening 19 and the crank is given one complete turn. This deposits a measured charge of material in the cup. rlhe milk, sirup, egg, or ot ier ingredient or ingredients are then added to the matted milk, and the lilled cup is then entered by h and over the spindle dT or thc'miier, with the vliiottom ot the cup at or above the level or the swinging support 5l. lVith the other hand the arm 5() isswung in a direction toward the cup until the support lslides beneath the cup and the clamp embraces the latter. rihe clerk then throws the switch Ll5 in a direction to energize the motor d2, and the ingredients or the drink are thoroughly agitated and mixed. is soon as the mining is complete, the clerk grasps the glass. with one hand, swings the support and clamp away from the glass with the other, withdraws the glass trom beneath the miner spindle, and passes it to the customer.

From the above it will be apparent that the deviceV of the present invention is of very simple structure, involvingl no complicated and elaborate internal mechanism; is very compact, requiring but a minimum of space on the counter; is easily and rapidly n'ianipulated, and presents a neat and attractive appearance. tric motor externally or the casing or housing of the holder and dispenser, any defect in the motor is easily gotten at and remedied without having to open up or partly dismantle theV casing` and its contained devices.

l am aware that it has heretofore been proposed to combine a motor driven drink dispenser and miner in a single organized structure, and l make no claim broadly to such an organization. The described relative arrangement of the dispenser, the' mixer, and the cup holder herein presented is, however, believed to be new and useful, and an improvement upon previous known devices of this general character.

Manifestly the details of the invention herein shown and described may be Vvari-I ously Amodified without changing the character oit the invention or lessening its advantages; and hence l reserve such variations and modifications as tall within the spirit and purview ol the appended claims. l claim: l. ln a combined drink dispenser and miX- er of the character described, the combination of a supporting standard, a casing mounted on said standard, a measured charge dispensing mechanismin said casing, anl ingredient receptacle mounted on and communicating with the interior el said casing, a motor mounted on and enteriorly of said casing, a depending miner spindle driven by said motor and a support for the drink receptacle ly locating the elecshiftalole to dispose its receptacle supporting portion beneath either said charge dispensing mechanism or said mixer spindle.
